Liassoscorpionides
''Liassoscorpionides'' is an extinct genus of scorpions from the Toarcian of Germany. It was found on the Posidonia Shale, on the so-called insect beds of Hondelage near Braunschweig, on a layer, as its name suggests, full of insect genera. ''Liassoscorpionides'' is the only confirmed jurassic scorpion discovered. The holotype consists of a partial body fossil, measuring 14.4 mm in length and 4.8 mm in width.Bode, A. (1951). Ein liassischer Scorpionide. Paläontologische Zeitschrift, 24(1-2), 58-65.

Jurassic Arthropods
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seppo Koponeni
''Seppo'' is an extinct genus of spiders, possibly of the superfamily Palpimanoidea, that lived about 180 million years ago, in the Early Jurassic (Lower Toarcian) of what is now Europe. The sole species ''Seppo koponeni'' is known from a single fossil from Grimmen, Germany. With the scorpion '' Liassoscorpionides'', it is one of the two only known arachnids from the Lower Jurassic of Germany. ''Seppo'' is the first unequivocal Early Jurassic spider, and was recovered from the ''Green Series'' member of the Toarcian Ciechocinek Formation. Description The spider was described from a single female specimen. It is unknown if was an adult. The carapace is unknown, and besides that has preserved bowed converging sides with a curved posterior margin with straight posterior border of the labium, with row of at least 12 peg teeth along the cheliceral furrow, no true teeth, scattered setae on anterior surface, and slender pedipalps. Legs are preserved, the first and second being much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clausthal Von Arnold Bode
Clausthal-Zellerfeld is a town in Lower Saxony, Germany. It is located in the southwestern part of the Harz mountains. Its population is approximately 15,000. The City is the location of the Clausthal University of Technology. The health resort is located in the Upper Harz at an altitude between 390 and 821 m above sea level. Geography Clausthal-Zellerfeld is located on the Upper Harz Plateau. The environment is less mountainous compared to most of the Harz, but only hilly. As a result, the immediate surrounding area is less wooded and there are more meadow areas. Scattered in and around Clausthal-Zellerfeld are numerous dams and streams of the Upper Harz Water Regale. The depression between Clausthal and Zellerfeld marks a natural "borderline". Southwest extends the "Small Clausthal valley".

Toarcian
The Toarcian is, in the ICS' geologic timescale, an age and stage in the Early or Lower Jurassic. It spans the time between 182.7 Ma (million years ago) and 174.1 Ma. It follows the Pliensbachian and is followed by the Aalenian. The Toarcian Age began with the Toarcian turnover, the extinction event that sets its fossil faunas apart from the previous Pliensbachian age. It is believed to have ended with a global cooling event known as the Comptum Cooling Event, although whether it represented a worldwide event is controversial. Stratigraphic definitions The Toarcian takes its name from the city of Thouars, just south of Saumur in the Loire Valley of France. The stage was introduced by French palaeontologist Alcide d'Orbigny in 1842, after examining rock strata of this age in a quarry near Thouars. In Europe this period is represented by the upper part of the Lias. The base of the Toarcian is defined as the place in the stratigraphic record where the ammonite genus '' Eoda ...

Posidonia Shale
The Posidonia Shale (german: Posidonienschiefer, also called Schistes Bitumineux in Luxembourg) geologically known as the Sachrang Formation, is an Early Jurassic (Toarcian) geological formation of southwestern and northeast Germany, northern Switzerland, northwestern Austria, southern Luxembourg and the Netherlands, including exceptionally well-preserved complete skeletons of fossil marine fish and reptiles.W.

Hondelage
Hondelage is a '' Stadtbezirk'' (borough) on the river Schunter in the north-eastern part of Braunschweig, Germany. History The village of Hondelage was first mentioned in documents in 1179. During the early 16th century, the farming village became property of the Imperial abbey Riddagshausen. In 1974, Hondelage, until then part of the disbanded rural district of Braunschweig, was incorporated into the city of Braunschweig and became a city district. Numerous fossils have been found in the Posidonia Shale of Hondelage, including Ichthyosaurus and Steneosaurus. Hondelagia, an extinct genus of snakefly Snakeflies are a group of predatory insects comprising the order Raphidioptera with two extant families: Raphidiidae and Inocelliidae, consisting of roughly 260 species. In the past, the group had a much wider distribution than it does now; s ..., is named after Hondelage, the only place it has been found so far.

Braunschweig
Braunschweig () or Brunswick ( , from Low German ''Brunswiek'' , Braunschweig dialect: ''Bronswiek'') is a city in Lower Saxony, Germany, north of the Harz Mountains at the farthest navigable point of the river Oker, which connects it to the North Sea via the rivers Aller and Weser. In 2016, it had a population of 250,704. A powerful and influential centre of commerce in medieval Germany, Brunswick was a member of the Hanseatic League from the 13th until the 17th century. It was the capital city of three successive states: the Principality of Brunswick-Wolfenbüttel (1269–1432, 1754–1807, and 1813–1814), the Duchy of Brunswick (1814–1918), and the Free State of Brunswick (1918–1946). Today, Brunswick is the second-largest city in Lower Saxony and a major centre of scientific research and development. History Foundation and early history The date and circumstances of the town's foundation are unknown. Tradition maintains that Brunswick was created through the merge ...

Prosoma
The cephalothorax, also called prosoma in some groups, is a tagma of various arthropods, comprising the head and the thorax fused together, as distinct from the abdomen behind. (The terms ''prosoma'' and ''opisthosoma'' are equivalent to ''cephalothorax'' and ''abdomen'' in some groups.) The word ''cephalothorax'' is derived from the Greek words for head (, ') and thorax (, '). This fusion of the head and thorax is seen in chelicerates and crustaceans; in other groups, such as the Hexapoda (including insects), the head remains free of the thorax. In horseshoe crabs and many crustaceans, a hard shell called the carapace covers the cephalothorax. Arachnid anatomy Fovea The fovea is the centre of the cephalothorax and is located behind the head (only in spiders).Dalton, Steve (2008). ''Spiders; The Ultimate Predators''. A & C Black, London.
